Mechanical, Interfacial, and Fracture Characteristics of Poly (lactic acid) and Moringa oleifera Fiber Composites

Three different processing techniques, extrusion, injection, and compression, were followed to fabricate poly (lactic acid) (PLA) and Moringa oleifera fiber (MOF) based composites. Chopped fibers of length 3–5 mm were used for the extrusion followed by injection molding, whereas long-length fibers (...
